THREAD-CUTTER FOR SEWlNG-lVlACHlNES.

SPECIFICATION forming part of Letters Patent No. 499,352, dated June 13,1893.

Application filed March 8, 1893. Serial No. 465.100. (No model.)

To all whom it may concern:

Be it known that I, JULIA E. SNAPP, residing at Danville, in the countyof Vermilion and State of Illinois, have invented certain new and usefulImprovements in Thread-Cutters for Sewing-Machines; and I do declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertain's tomake and use the same, reference being had tothe accompanying drawings,and to the figures of reference marked thereon, which form a part ofthis specification.

My invention relates to thread cutters for sewing machines: and itsobjects are: first, to provide an effective thread cutter therefor;second, to dispose the same readily in the necessary location; third, toattach the same to, or detach it from, the presser foot at will; fourth,to provide for the easy replacement of the cutter on the means of itsjoinder to the presser foot; and fifth, to accomplish these ends withstructural simplicity and economy I accomplish these ends by the deviceillustrated in the accompanying drawin gs, in which Figure 1, representsa perspective view of a detached presser foot, showing the applicationof myinvention thereto. Fig. 2, shows a side view of a screw, having thecutter adjusted thereon; and Fig. 3, is a front View of said screw,illustrating the contour of the cutter.

The same designations indicate corresponding parts in all the views.

The presser foot 1, of ordinary form, has a threaded aperture in itscollar, to engage the shank 4 of the screw 2. A knife-edged hexagonalcutter plate 3, having tapering termini, is screwed on the shank 4, soas to become practically an integral part of its head 2..

When it is desired to cut the thread it is simply necessary to pass itbetween the outer wall of the collar of the presser foot, and the innerwall of the screw-head 2, so that it will inevitably come in contactwith the cutter 3 and sever the thread.

Having thus fully described my improvement, what I claim is The presserfoot 1 of an ordinary sewing JULIA E. SN APP.
